It was a boneheaded mistake. Math dictates that if you go for it with inches left and your main back is averaging 6 yards a carry that you're likely going to get it. Actually, every UAB running back was averaging at least 6 yards a carry in the game. UAB running backs only had 7 plays out of 31 that went for 0 or negative yardage all game. So, 77.4% chance for positive yardage. You sacrifice potentially 30-35 yards on defense if you miss for a 77% chance of automatically winning the game...and you only need to get literal inches. The vast majority of non UAB/UTSA fans can see that UAB gave that game away.
That doesn't take away what UTSA has done. UTSA is having a special year and sometimes you just need the other team to bail you out. Happened to us in years past. And frankly we don't deserve to win these games or be the division champion averaging 100 yards of penalty per game. Ridiculous
I can appreciate someone who does the math and throws percentages and such into the discussion because I'm a retired math teacher. So I wanted to add one more thing to my previous response to your post in lieu of those percentages you provided.
I did some research and found that when teams have a 4th and 1 or less, they actually convert nearly 70% of the time. The data I found for that pertained to the NFL, but I would imagine the number wouldn't be very different for college.
I also came across an analysis of how scoring is related to field position though. And in the analysis, it was found that teams starting at about their own 25-yard line scored a touchdown on the possession roughly 18% of the time. Time was not an element thrown into the analysis though, and I would expect that 18% number to actually be around 10% or less if the team had only a minute to score with no remaining time-outs. I linked it below, and though I believe it also pertained to the NFL, as with the other, I would also expect it to be similar for college.
So what we had on that 4th down play was essentially this... You have about a 70% chance of making it if you go for it, but you have at least a 90% chance of keeping your opponent from scoring a TD if you punt it, and force them to go 75 or more yards with only a minute to go and no time-outs.

You still have to calculate the risk in comparison to the opponent instead being on your 42 yard line vs the 75ish yard line. It wasn't as simple as either you get the conversion and win or don't and auto lose. You either get the conversion at a 70% clip AND the opponent then has to score a TD from your 42 yard line for you to lose the game, or you concede the 70% chance of auto-winning the game and the opponent has to score from their own 20ish yard line (I think 23 yard line in this case).
So, at least a 70% chance of automatically winning the game and if you fail, the opponent still has to drive 42 yards to win. Or the opponent has to drive 77 yards to win. Of course Clark had no idea where the punt would land.
For touchdown results by starting position I see according to bcftoys (204,802 college FBS offensive drives):
Own 23 yard line: 21.9% chance of scoring a TD
Opponent 42 yard line: 39.2% chance of scoring a TD
Given we have a 70% chance of auto winning the game (honestly, converting the inches would be much higher probability than this) if we try to convert the 4th and inches, 70% to win + 18.24%/30% chance to win if you have to stop a touchdown drive at the 42 yard line:
With Clark's decision to punt: 78.1% chance of winning the game.
Going for the conversion: 88.24% chance of winning the game.
So unless I'm doing the math wrong, pretty big difference there and just overall a dumb decision, especially considering the running game success. And again, I think this is worst case scenario, the conversion would probably have an even higher conversion clip.
Also, even if the punt managed to land at UTSA's 1 yard line: 86.1% chance of winning the game (only a 13.9% chance of scoring a TD at your own 1 yard line)
Of course you still have to factor in time remaining and everything else (though that would still apply to the 42 yard drive versus 77), but obviously this is about as close as we can get. I imagine the stats still lean towards trying to convert the 4th and inches regardless.
Edit: and just being honest here, the chances of converting something like 2-4 inches is probably around 90% in this game. So you're probably talking something like a 96% chance to win the game on going for the 4th down conversion versus a 78% chance to win with the punt. It's even worse when you take in where the ball actually was. Clark's decision improved UTSA's odds of winning dramatically.
